The Landscape Architecture of Crisis

The invisibility of underground fires makes them particularly surreal and difficult to imagine: flames with no real room to flicker, moving slowly forward through the planet, relentlessly burning their way ever deeper into the landscape from below.

Whether that fire was caused by the ignition of a coal seam—as in Centralia or, my favorite example, in Australia’s Burning Mountain—or because subterranean strata of human-generated trash have caught fire, these events make for an especially spectral presence in the landscape. They remain entirely out of view except for the haze of their atmospheric effects, as they fill the air above with toxic gases.

As the AP reports, “Beneath the surface of a St. Louis-area landfill lurk two things that should never meet: a slow-burning fire and a cache of Cold War-era nuclear waste, separated by no more than 1,200 feet.”

It’s worth pointing out that “the waste was illegally dumped in 1973 and includes material that dates back to the Manhattan Project, which created the first atomic bomb in the 1940s.” In many ways, then, this was an obvious problem just waiting to reassert itself.

An “emergency plan” has now kicked into gear to help fend off the potentially “catastrophic event” that would occur if these two things meet—the dormant deposit of nuclear waste and the respiring event of the underground fire.

In effect, this plan is a massive undertaking of design: it is landscape architecture as a tool against crisis.

New structures called “interceptor wells” are being constructed, for example, to maintain a kind of thermal quarantine line between the fire and the nuclear waste—however, the fire already appears to have circumvented these buffers, at least according to the AP. For example, some safety reports from the site have allegedly “found radiological contamination in trees outside the landfill’s perimeter,” implying that the nuclear waste has already, in at least some capacity, entered the biosphere, and “another showed evidence that the fire has moved past two rows of interceptor wells and closer to the nuclear waste.”

Yet another report ominously claims that the management company in charge of the landfill simply “does not have this site under control.”
